[Pyobjc-dev] Using global functions and constants?

[Orestis M. <or...@or...>]

Hello,

I'm trying to use IOBluetooth and IOBluetoothUI. I've figured out  
using the Obj-C part (using objc.loadBundle) but IOBluetooth uses some  
external functions, like IOBluetoothNSStringToDeviceAddress in  
IOBluetoothUtilities. I can't find a way to use this.

I've tried using gen_bridge_metadata but I get a compiler error.  
Checking, I've seen that there is a IOBluetooth.bridgesupport file  
inside the framework resources but it doesn't contain the above  
function. After looking around, I've tried using a constant it *does*  
contain, ie kBluetoothFeatureEncryption, but Python still can't find it.

I'm using:

import objc as _objc

_objc.loadBundle('IOBluetooth', globals(),
  bundle_path=u'/System/Library/Frameworks/IOBluetooth.framework')

in IOBluetooth.py and

from IOBluetooth import *

in my main class.

The documentation on wrapping global functions/constants is *severely*  
lacking, so any help appreciated :)

Hi, I just found this in an email from Bob Ippolito a while back. (at
http://www.mail-archive.com/pyt...@py.../msg02013.html )
Try using objc.loadBundleFunctions.
if IOBluetoothNSStringToDeviceAddress is pretty simple, that might work.

Here's the example from the email:

bundle = NSBundle.bundleWithPath_('/System/Library/Frameworks/Carbon.framework')
objc.loadBundleFunctions(bundle, globals(), (
     ('SetSystemUIMode', 'III', " Sets the presentation mode for
system-provided user interface elements."),
))

Thanks, I've made some progress. Here is my code:


bundle =3D NSBundle.bundleWithPath_('/System/Library/Frameworks/=20
IOBluetooth.framework')
objc.loadBundleFunctions(bundle, globals(),(
         ('IOBluetoothNSStringToDeviceAddress', "i:@^@","blah test" ),
         ))
print IOBluetoothNSStringToDeviceAddress

This yields: <objc.function object at 0xdc97a0> which I suppose means =20=

that the function was loaded.
However, if I follow with:

address =3D "00-1d-28-e1-bd-90"
out =3D None
print IOBluetoothNSStringToDeviceAddress(address, out)

I get:
TypeError: Need 3 arguments, got 2

I tried changing the signature to i:@o^@ , to account for the output =20
parameter but I get a segmentation fault.

The Objective-C function signature is:

extern IOReturn IOBluetoothNSStringToDeviceAddress( NSString =20
*inNameString, BluetoothDeviceAddress *outDeviceAddress );

I've tried to divine the method signature from =
http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/Artic=
les/chapter_13_section_9.html#/=20
/apple_ref/doc/uid/TP30001163-CH9-TPXREF165

but I don't think I've succeeded...
